Abstract
A field experiment was conducted at Krishi Vigyan kendra, Sawaimadhopur, Rajasthan, India in two consecutive years during 2018-19 and 2019-20 on Zone III –B of Rajasthan, India. In this experiment was performed in randomized block design which includes four treatments of weed control i.e. weedy check (T1), Hand weeding at 25 DAS (T2), Hand weeding at 25 & 45 DAS (T3), Pre emergence application of Pendimethaline @ 1.0 kg a.i. ha-1 (T4) and replicated five times. Results revealed that Weed Density (no m-2) 60 days after sowing, Dry weight (kg ha-1) 60 days after sowing, weed control efficiency (%) and weed index found lowest in two hand weeding at 25 and 45 days after sowing fb Pre emergence application of Pendimethaline @ 1.0 kg a.i. ha-1 (T4) during both the years during 2018-19 and 2019-20, respectively. Highest seed yield (2341 kg ha-1) and (2431 kg ha-1) was found under two hand weeding (25 & 45 days after sowing) during 2018-19 and 2019-20 respectively.
